Aim: Enuresis is defined as involuntary or intentional repeated voiding of urine into clothes or bed at least twice a week for a period of three consecutive months in children older than five years old. It is one of the most frequent chronic childhood disorders. The aim of this study was to investigate the frequency of behavioural problems in children with enuresis. Material and Methods: The research compared 30 children aged between 7 and 11 years who had consulted to Bakırköy Prof. Dr. Mazhar Osman Mental Health and Neurological Diseases Training and Research Hospital, Child and Adolescent Psychiatry Clinics and diagnosed with enuresis with their 30 peers who were randomly selected from a state elementary school. The Child Behaviour Checklist was applied to both groups. Results: The subdimension scores of both groups were compared, it was observed that children with enuresis had higher scores compared to their peers in all sub-tests except for the Sluggish Cognitive Tempo, Anxiety Disorders, and Obsessive Compulsive Disorder sub-tests. Enuretic children had higher scores in externalization (p<0.001), internalization (p=0.001) and total problem (p<0.001) scales. Conclusion: The results of this study indicate that children with enuresis exhibit behavioral problems with a higher rate compared to their healthy peers. The results are in line with the literature. Moreover, compared to the results of the studies conducted in different countries, significantly higher scores in internalization problems were obtained. It was thought is possible that this might be related with cultural factors. However, these findings need to be verified with data from larger scale studies. [ABSTRACT FROM AUTHOR]
